Progress should be continual and consistent.  

Continual means it is always increasing.  Consistent means learning is happening every day.

10% progress is expected each month.

You should  have a minimum of 90% progress by May 15th to be considered complete this school year.

Some programs are based on usage and not progress.  (For example. Rosetta Stone is an exploratory course.)  In these courses, I look for consistent use as the gauge for progress.

If you are struggling to make progress, Mrs. Charlton will make a plan with you to get on track.

Note on Performance:  Many people get confused between the performance percentage and the progress percentage.  Performance is how well you did (think A, B,  or C grades in more traditional settings).  Progress is how much you are done. (For example, I am halfway done with my course.)
